I'm pretty sure (maybe, kinda, I'm old, memory sucks) that only BZB Scrap, BZB Brute and Louis Cypher were fully T4ed back before the snap. It wasn't even remotely worth it to bother doing so with any other character. Now? It takes MAYBE two weeks for me to get a character to 50, fully PvPed/Purpled/IOed, T4ed AND have all 4 passive accolades.
This is why I find it so difficult to accept that majority of players are still running around with SO only builds. Sure... maybe on the way to 50, but after that? Nah, citation seriously needed.
